Physical Review Letters, 122(16), 162002–162002. https://doi.org/10.1103/PhysRevLett.122.16200210.1103/PhysRevLett.122.162002https://hdl.handle.net/10433/22801We report on the first computation of the strong running coupling at the physical point (physical pion mass) from the ghost-gluon vertex, computed from lattice simulations with three flavors of domain wall fermions. We find , in remarkably good agreement with the world-wide average. Our computational bridge to this value is the Taylor-scheme strong coupling, which has been revealed of great interest by itself because it can be directly related to the quark-gluon interaction kernel in continuum approaches to the QCD bound-state problem.application/pdfenAttribution-NonCommercial 4.0 Internationalhttp://creativecommons.org/licenses/by-nc/4.0/LatticeQCDQuantum chromodynamicsStrong interactionjournal articleopen access
